From March 12, 2024, to March 19, 2024, SAMR solicited opinions on the implementation details of quality supervision and spot checks for 147 types of products, including sofa products. The requirements of this implementation detail are as follows:
1. Sampling Method:
Samples shall be randomly selected from the products awaiting sale by the sampled producers and sellers. Random numbers can generally be generated using methods such as random number tables. Two samples shall be taken from each batch of products, with one sample used for inspection and the other as a backup sample.
2. Inspection Items:
l Product materials and processing: Wood components, metal components, upholstery materials, rust prevention treatment, friction noise, and apparent density/seat surface of foam plastics, resilience (except slow rebound foam plastics), compressive permanent deformation, recycled bonded foam plastics.
l Surface coating physicochemical properties: Adhesion, abrasion resistance, thermal shock resistance, impact resistance of wood component paint film coatings, adhesion and corrosion resistance of metal component surface coatings, corrosion resistance of metal component electroplating coatings, color fastness, pilling resistance, abrasion resistance of textile fabrics, friction color fastness of leather/reconstituted leather, abrasion resistance, coating adhesion of artificial leather.
l Mechanical properties: Durability of sofa seats, backs, and armrests.
l Limits of harmful substances: Formaldehyde, benzene, toluene, xylene (sum of ortho-, meta-, and para-xylene), total volatile organic compounds (TVOC) emission.
l Safety performance: Structural safety, flame retardancy.
3. Main Standards adopted:
l GB 17927.1-2011 Upholstered furniture - Assessment of the resistance to ignition of the mattress and the sofa - Part 1: Ignition source: smoldering cigarette
l GB 17927.2-2011 Upholstered furniture - Assessment of the resistance to ignition of the mattress and the sofa - Part 2: Ignition source: match flame equivalent
l QB/T 1952.1-2012 Upholstered furniture - Sofa
l QB/T 1952.1-2023 Upholstered furniture - Sofa
4. Judgment Principles:
If any of the inspection items or more are found to be unqualified, the sampled product shall be judged as unqualified.
l If the quality requirements indicated by the inspected product are higher than the standards cited in this document, the judgment shall be based on the quality requirements indicated by the inspected product.
l If the quality requirements indicated by the inspected product are lower than the mandatory standard cited in this document, the judgment shall be based on the mandatory standards.
l If the quality requirements indicated by the inspected product are lower than or include the recommended standards cited in this document, the judgment shall be based on the quality requirements indicated by the inspected product.
Product quality supervision and spot checks are one of the market supervision activities stipulated in the "Interim Measures for the Administration of Product Quality Supervision and Spot Checks." For products with inspection conclusions indicating non-compliance, the sampled producers and sellers shall immediately cease production and sales of the same product. Sampled producers and sellers with serious quality issues in the sampled products shall be dealt with by the county-level market supervision and administration department in accordance with relevant laws and regulations; where there are no provisions in laws and regulations, a fine of up to 30,000 CNY shall be imposed; if it constitutes a crime and criminal responsibility needs to be investigated according to law, it shall be transferred to the public security organs according to relevant regulations.
